I just wanted to followup of this thread. I filed a ticket with all of
these issues since many of them are potential bugs that should be
fixed for v1.5 (and v1.4 if possible). The link to the ticket is below
if you wanted to follow the progress:
https://svn.open-mpi.org/trac/ompi/ticket/2397

Thanks again for the bug report. Sorry that it has taken me so long
to get back to it (Dissertation writing really takes the wind out of
ones sails). I hope to make forward progress on these and other C/R
related bugs and feature requests over the next month or so.
